and workflow-template decisions.
* Use roles, includes, imports, and Ansible Content
Collections
in reusable automation designs.
* Generate and assess network configuration with Jinja2,
ansible.netcommon, and configuration backups.
* Troubleshoot realistic automation failures and select
technically appropriate corrective actions.
* Identify weak EX457 objective areas and assess readiness
through six progressively challenging practice tests.
REQUIREMENTS
* Formal prerequisite: No mandatory prerequisite is required
to
enroll in this practice-test course.
* Recommended: Understand networking fundamentals, routing,
and
basic router/switch configuration.
* Recommended: Be familiar with network-device command-line
administration and SSH.

extensive objective-based assessment.
* Candidates who want to identify weak EX457 objective areas
before continuing hands-on preparation.
DESCRIPTION
EX457: Red Hat Certified Specialist in Ansible Network
Automation is a performance-based certification focused on
managing network infrastructure with Red Hat Ansible
Automation
Platform. This practice-test-only course provides structured
assessment across the objective areas represented in the
completed course blueprint. The course contains six domain-
focused practice tests with 250 questions each, for 1,500
questions in total. Questions move from foundational
recognition
to applied configuration, troubleshooting, workflow decisions,
and realistic network-automation scenarios. Each question has
four answer options, one correct answer, a separate
explanation
for every option, a detailed overall explanation, and an
identified course domain. Course Overview Course type:
Practice-
test-only course Practice tests: 6 Questions per test: 250
Total
questions: 1,500 Question format: Multiple-choice with four
options and one correct answer Difficulty: Mixed ? beginner,
intermediate, and advanced questions in every test Structure:
Topic- and domain-focused tests rather than one repeated full-
syllabus mock format Detailed overall explanations: Included
Incorrect-option explanations: Included Domain identification:
Included Video lessons: Not included What This Course Covers
Red
Hat Enterprise Linux command-line work, file editing, shell
commands, and SSH Inventories and Automation content navigator
Ansible playbooks, Git workflows, variables, network facts,
and
filters Loops, conditional execution, task failures, and
troubleshooting Automation controller credentials, projects,
jobs, and workflow templates Includes, imports, roles,
reusable
network automation, and Ansible Content Collections Jinja2
configuration generation, ansible.netcommon workflows,
configuration backup, and multivendor network administration
Scenario analysis involving configuration choices, failure
diagnosis, operational validation, and safe network-automation
decisions What Makes These Assessments Useful The 1,500
questions were independently created for this course and are
organized to assess different learning objectives rather than
repeat the same fact with minor wording changes. The course
includes realistic scenarios, progressive difficulty, detailed
correct-answer reasoning, explanations for incorrect choices,
and domain labels that can help you identify areas requiring
more review. Because the real EX457 examination is hands-on
and
performance-based, these multiple-choice assessments should be
used as a knowledge and decision-making supplement to
practical
Ansible work. They are designed to help you practise technical
reasoning, not replace hands-on preparation. How to Use This
Course Review the official EX457 objectives before beginning.
Attempt Practice Test 1 without assistance, then continue
through the tests in order. Review every correct, incorrect,
skipped, and uncertain response using the option and overall
explanations. Revise weak objective areas and practise the
related Ansible tasks hands-on. Retake the relevant test under
your configured timed conditions after revision. Sample
Question
A network team needs to run a read-only operational CLI
command
on supported network devices using a platform-independent
ansible.netcommon module and capture the returned output.
Which
module is the most appropriate choice? A.
ansible.netcommon.cli_config B. ansible.netcommon.cli_command
C.
ansible.builtin.template D. ansible.builtin.copy Correct
Answer:
B. ansible.netcommon.cli_command Explanation:
ansible.netcommon.cli_command is designed to send operational
CLI commands to supported CLI-based network devices and return
their output. It fits a read-only command-retrieval workflow.
Why the Other Options Are Incorrect: A: cli_config is intended
for applying text-based network configuration rather than
simply
retrieving operational command output. B: This is the correct
choice because it sends CLI commands and returns the result.
C:
template renders Jinja2 content; it does not execute a network
CLI command by itself. D: copy transfers files and is not the
platform-independent network command module. Exam Domain:
Network Administration Automation Difficulty: Intermediate
Skill
Tested: Application Who This Course Is For This course is
intended for EX457 candidates, network administrators,
infrastructure engineers, network-automation engineers,
Ansible
practitioners, and learners who have completed relevant
training
or self-study and want extensive objective-based practice.
Recommended Prerequisites There is no mandatory prerequisite
for
enrolling in this practice-test course. Helpful preparation
includes networking fundamentals, routing and switch/router
configuration, network-device command-line experience, Linux
command-line familiarity, basic Git usage, and an
understanding
of Ansible Core and Red Hat Ansible Automation Platform.
